Herpes simplex
Herpes is an infection caused by herpes simplex virus 1 or 2. It
primarily affects the mouth or genital area.
There are two different strains of herpes simplex viruses. Herpes simplex virus type 1
(HSV-1) is usually associated with infections of the lips, mouth, and face. It is the most
common herpes simplex virus among the general population and is usually acquired in
childhood.

Herpes simplex virus 2 (HSV-2) is sexually transmitted and is usually associated with
genital ulcers or sores. Individuals may, however, harbor HSV-2 and not have developed any
symptoms. Up to 30% of U.S. adults have antibodies against HSV-2. Cross-infection of type
1 and 2 viruses may occur from oral-genital contact. | |
